PyGrub + ZFS: getbootstring. How it works?
I have NexentaCP2 (Opensolaris b104+).
Parameters for the kernel:
''zfs-bootfs=syspool/rootfs-nmu-000,bootpath=/xpvd/xdf@0:a''
Pygrub returns:
''zfs-bootfs=syspool/30,bootpath=/xpvd/xdf@0:a''
Result: Boot with pygrub don''t work.
What is "30" in syspool/30 ?

Xen 4.0.1, tap vs tap2, blktap2 documentation, and gentoo-xen-kernel problem
Hi,
I''ve been testing Xen 4.0.1 with kernel 2.6.34.5 +
http://gentoo-xen-kernel.googlecode.com/files/xen-patches-2.6.34-4.tar.bz2,
and one of the things that I noticed immediately is there are two
problems with tapdisk and this combination.
First, the syntax "disk = [''tap:tapdisk:aio: ..." no longer works.
When tested with HVM domU, it boots, but there was no disk

blktap2: help please?
Hi guys,
i''ve just installed xen 4.0. Since always blktapctl has never worked on
my dell 1950III. I even posted a bug but so far i can''t use tap:aio or
similar.
I thought that with version 4 this would work, but it didn''t. I still
see syslog errors from blktap version 1.0.0.
Today i wanted to try version 2 I found on the xen/tools source folder.
I compiled the source

Xen4CentOS python-virtinst version issue, blktap2 problem
Hello,
It seems currently when you "yum update" CentOS 6.6 Xen host you end up getting python-virtinst from c6 base repo:
python-virtinst-0.600.0-24.el6.noarch
and not from Xen4CentOS repo, because the version there is "older": 0.600.0-19.
.. which means the centos/xen-specific patch in python-virtinst is "lost". (default to tap2 instead of tap1, to make blktap2

How to configure so as to use the blktap/blktap2 module in XEN
Hi,mail list members,
As needed by my test, blktap/blktap2 modules have to work after new VMs start.Maybe the line about disk in the vm creation configure file is the right position where I should be supposed to specify the function of blktap/blktap2 modules.But specifically I don''t know how to configure the disk line.Who can help me?

Mounting filesystems with blktap2
For those wanting to know how to mount filesystems through blktap2
here is how you do it, as I couldn''t find it fully documented.
The instructions on the blktap2 readme file are rather out of date.
You can mount them under Dom0 like so.
e.g. to mount a vhd file,
sudo xm block-attach 0 tap2:vhd:/home/xen/xenwin7-persist.vhd xvdb w 0
Now the device should appear under /dev

Remus blktap2 issue
Hello,
I have been playing around with Remus on Xen 4.0.1, attempting to fail-over
for an HVM domU.
I''ve run into some problems that I think could be related to tapdisk2 and
its interaction with how one sets up Remus disk replication in the domU
config file.
A few things I''ve noticed:
-The tap:remus:backupHostIP:port|aio:imagePath notation does not work for
me, although this

Custom block script started twice for root block but only stopped once
Hi,
I''m using a custom block script in my xen setup and when started, it
creates a new device node pointing to some network resources.
Now I noticed that the script is called twice for the root block, the
first time for pygrub most likely, but is only stopped once ... I
don''t mind creating two devices node, but then I need to destroy both

Is this a known issue ?

BLKTAPCTRL[2375]: blktapctrl_linux.c:86: blktap0 open failed
I''m getting this message (subject line) in daemon.log every time I
start or restart xend. I''m not sure if this is related to the fact
that I cannot boot up my Windows domU from a VHD file. The Windows
domU was working fine with Xen 4.0.0 (with 2.6.32.14 dom0 kernel).
When I upgraded to Xen 4.0.1-rc4 (with 2.6.32.16 dom0 kernel), I can
no long boot the Windows domU from VHD. The
